Hello. I recently bought a 2000 polaris trail boss 325 four stroke lightly used . it sat most off the time. before I used it much I did a full lube & oil change . to my suprise upon removeing the transmition drain plug. NO FLUID at all not one drop. Every thing seems ok no problems no unusual noise ects. what if any are the long or short term afects off this .i am shure the atv was ridden manny times for short distances in this condition. thanks chuck.
